Add Exception in Firewall

It is also possible that the Windows Firewall that you guys are using might be blocking your connection to the server. Thus, in this step, we will be adding an exception in the Firewall for some executables in the Minecraft folder and that need internet access. For that:

• Click on the start menu and choose the Settings icon.
• In the Settings, just tap on the “Updates & Security” option.
• Choose the “Windows Security” from the left pane and then select the “Firewall & Network Protection” option.

• Now permit both the  Java executables located inside the folder in the same way.
• Then repeat the process again and rather than clicking “Allow another app” after choosing the “change” option simply scroll down the list of apps available. And permit all the “Java Platform SE Binary” options via both the “Private” and “Public” networks.
• Open the Minecraft launcher, then just try to connect to the server, and check in order to see if the issue persists.

Resolve Conflicts with VPN | Connection Error on Minecraft

Method 1: Uninstall VPN Client

Since a VPN client masks your IP address, then it may also trigger the said error. Thus, uninstalling the VPN client might help fix the io.netty.channel.AbstractChannel$AnnotatedConnectException connection error in Minecraft

To delete all the data and files associated with the VPN client in one go. We have used Revo Uninstaller in this method actually.

• Open Revo Uninstaller and navigate to your VPN Client.
• Now, select the VPN Client and click on Uninstall from the top menu bar.

Add the IP address and Port Before Connecting

If the IP address that you guys are using is not a static one. It will change each and every couple of days or whenever the Internet Connection is reset. Thus, in this step, we are going to check the IP address and the correct port for the game and then add it to the Minecraft Launcher. For that:

• Click on the search bar on the Windows toolbar and just type in “Command Prompt“.
• Right-click on the icon and choose “Run as Administrator“
• Now type in “ipconfig” and also note down the “IPV4 Address“.
• Also, Navigate to the “Minecraft Servers folder>Maxwell (some random numbers)> MinecraftServer” and then open the “Server Properties” text document.
• Also, note down the “Server Port” listed there. In our case it was basically “25565” it should be similar in most cases but in some, it is not.

• Now open up Minecraft and then navigate to the “Play Multiplayer” option.
• Choose the server which you want to join via tapping on it and choose “Edit” from the below options.
• The server name can also be according to your preference, however, the “Address” needs to be the IPV4 address. That we noted, and the port number such as “XXX.XXX.X.X:25565” the “25565” is the port number and it may also vary.
• Tap on “Done“, and click on “Refresh” and check to see if the issue persists.

Note: There are some apps that are generally incompatible with some elements of Minecraft and cause issues along with it. The list of applications is also available here. If these installing on the PC on which the server is running or on your computer you guys will continue to face issues along with the game.
